Cognitive-behavioral therapy for geriatric compulsive hoarding

This investigation examined response to a manualized cognitive-behavioral therapy (CBT) protocol for compulsive hoarding (Steketee & Frost, 2007) in a sample of 12 adults over age 65. All participants were cognitively intact, not engaging in any other psychotherapy, and had compulsive hoarding as their primary problem. All received 26 sessions of individual CBT over the course of 17 weeks. The primary outcome measures were the Savings Inventory-Revised and UCLA Hoarding Severity Scale, which were administered at baseline, mid-treatment, post-treatment, and 6-month follow-up. Other outcomes included Clinical Global Impression (CGI) scores, depression, anxiety, disability, and clutter image ratings. Results demonstrated statistically significant changes on hoarding severity and depression. However, only three of the twelve participants were classified as treatment responders at post-treatment, and their gains were not maintained at 6-month follow-up. CGI, anxiety, disability, and clutter ratings were unchanged at post-treatment and follow-up. No participants dropped out, but homework compliance was variable and correlated with decreases in hoarding severity. Findings suggest that older adults with compulsive hoarding may require an enhanced or alternative treatment.

Group cognitive-behavioral therapy for hoarding disorder: an open trial

Although cognitive-behavioral therapy (CBT) appears to be a promising treatment approach for hoarding disorder, treatment to date has been quite labor intensive. The goal of this study, therefore, was to assess the potential effectiveness of group CBT for hoarding, without home visits by the clinician. Forty-five individuals with hoarding disorder enrolled in either a 16 or 20 session program of group CBT; 30 (67%) completed treatment. Using mixed-effects models to account for missing data, we report data from 35 (78%) participants who provided enough data for analysis. Participants demonstrated significant improvements in hoarding symptoms, as well as symptoms of depression and anxiety, and quality of life. Improvements in hoarding symptoms were comparable to two published clinical trials on individual CBT for hoarding disorder. Results of this study suggest that group CBT for hoarding, without home discarding sessions by the clinician, may be an effective treatment option with the potential advantage of increasing treatment access by reducing clinician burden and cost of treatment.

Enhancing group cognitive-behavioral therapy for hoarding disorder with between-session Internet-based clinician support: A feasibility study

OBJECTIVE

Hoarding disorder (HD) is difficult to treat. In an effort to increase efficacy and engagement in cognitive-behavioral therapy (CBT), we developed and evaluated a novel intervention comprising group CBT combined with between-session Internet-based clinician support for people with HD.

METHOD

Twenty participants with HD received group CBT combined with an Internet-support system enabling therapist-participant communication between group sessions.

RESULTS

The treatment was associated with a significant reduction on the Saving Inventory-Revised (SI-R) and a large effect size (Cohen's d = 1.57) was found at posttreatment. Treatment gains were maintained at the 3-month follow-up. Group attendance was high and no participants dropped out from treatment prematurely. Between-session motivational support from the therapist was most frequently mentioned as the main strength of the system.

CONCLUSION

The results of this study support adding Internet-based clinician support to group CBT for HD to increase treatment adherence and, potentially, improve the overall efficacy of CBT.

Hoarding disorder in older adulthood

OBJECTIVE

Hoarding disorder (HD) is a chronic condition associated with moderate to severe impairment in health and functioning. HD has been primarily studied in midlife adults, and there is limited research on HD in late life.

METHODS

In this review, we summarize research on the presentation and characteristics of HD and hoarding symptoms in older adults, including evidence for associated impairment in daily functioning, physical health, and cognitive function. Finally, we review the evidence available for intervention outcomes for treating HD in older adults.

RESULTS

Geriatric HD is characterized by severe functional impairment, medical and psychiatric comorbidities, and cognitive dysfunction.

CONCLUSION

There is a lack of randomized controlled trials investigating evidence-based treatments for geriatric HD.

Implementation and evaluation of a community-based treatment for late-life hoarding

OBJECTIVES

The objective of this paper was to examine the implementation and effectiveness of a community-based intervention for hoarding disorder (HD) using Cognitive Rehabilitation and Exposure/Sorting Therapy (CREST).

DESIGN

This was a mixed-method, pre-post quasi-experimental study informed by the Practical, Robust Implementation and Sustainability Model for implementation science.

SETTING

Program activities took place in San Diego County, mainly within clients' homes or community, with some activities in-office.

PARTICIPANTS

Participants were aged 60 years or older, met eligibility for Medi-Cal or were uninsured, and met criteria for HD.

INTERVENTION

A manualized, mobile protocol that incorporated CREST was utilized.

MEASUREMENTS

The Clutter Image Rating and Hoarding Rating Scale were used as effectiveness outcomes. An investigator-created staff questionnaire was used to evaluate implementation.

RESULTS

Thirty-seven clients were reached and enrolled in treatment and 15 completed treatment during the initial 2 years of the program. There were significant changes in hoarding severity and clutter volume. Based on the initial 2 years of the program, funding was provided for expansion to cover additional San Diego County regions and hire more staff clinicians in year three.

CONCLUSION

Preliminary data suggest that the CREST intervention can be successfully implemented in a community setting with positive results for older adults with HD.

Group cognitive-behavioural therapy for hoarding disorder: Systematic review and meta-analysis

Previous meta-analysis has reported the rate of reliable and clinically significant changes in hoarding disorder (HD) after cognitive-behavioural therapy (CBT) based on the classical CBT model of HD, as between 42% and 25%. However, in this analysis, different types of therapy (group vs individual, G-CBT and I-CBT, respectively), different providers (psychologist vs nonpsychologist), and different diagnosis (HD vs hoarding behaviour) were analysed together. Hence, it remains unclear if reported rate of changes was due to limits of the CBT model of HD or due to the fact that different applications of the model were analysed together. The aim of this meta-analysis is to highlight shortcomings in the description of existing approaches in G-CBT in HD and provide an up-to-date review of the current state of efficacy. We searched references for treatment trials of G-CBT for HD in adults with object hoarding, where treatment was conducted by a professional in PubMed, PsychINFO and Web of Science databases, and ResearchGate (for grey literature). Data on participants, treatment modalities, and outcomes were extracted; treatment effect-size was meta-analysed. Five hundred and forty-three references were found; after title and abstract screening, eight articles (178 participants) were retained of which seven were included in the meta-analysis. G-CBT showed improvement of HD severity at posttreatment (Hedge's g = 0.96). The rate of clinically reliable changes across groups of treatment was 21%-68% (M = 36.7%; SD = 12.1%). The meta-analyses showed a statistically but not clinically significant impact of age on effect-size. No publication bias was found. There is strong evidence supporting the efficacy of G-CBT including modified or extended versions of classical G-CBT protocols. However, controlled trials with follow-up assessment are needed to evaluate long-term G-CBT efficacy for HD. As well, the rate of clinically significant changes is low; further research on the HD model could improve the efficacy of G-CBT.

Recent Advances in Research on Hoarding

PURPOSE OF REVIEW

The purpose of the following paper is to review recent literature trends and findings in hoarding disorder (HD). Our goal is to highlight recent research on etiology, associated features, and empirically based treatments.

RECENT FINDINGS

Recent literature has added support for cognitive differences as a risk factor for HD; however, there is evidence that individuals with HD may overestimate their level of cognitive impairment. Several associated features have been highlighted in recent studies, including emotion regulation, intolerance of uncertainty and distress intolerance, and attachment. Finally, several psychotherapeutic treatments for hoarding have been recently validated, including group-based therapy and treatments using the cognitive-behavioral model. Although recent research demonstrates that hoarding can be effectively treated with available psychotherapeutic modalities, the effectiveness of current treatments is not as robust as that for other psychiatric disorders and more work is needed in treatment precision.

Unbending mind: Individuals with hoarding disorder do not modify decision strategy in response to feedback under risk

Cognitive-behavioral models of hoarding disorder emphasize impairments in information processing and decision making in the genesis of hoarding symptomology. We propose and test the novel hypothesis that individuals with hoarding are maladaptively biased towards a deliberative decision style. While deliberative strategies are often considered normative, they are not always adaptable to the limitations imposed by many real-world decision contexts. We examined decision-making patterns in 19 individuals with hoarding and 19 healthy controls, using a behavioral task that quantifies selection of decision strategies in a novel environment with known probabilities (risk) in response to feedback. Consistent with prior literature, we found that healthy individuals tend to explore different decision strategies in the beginning of the experiment, but later, in response to feedback, they shift towards a compound strategy that balances expected values and risks. In contrast, individuals with hoarding follow a simple, deliberative, risk-neutral, value-based strategy from the beginning to the end of the task, irrespective of the feedback. This seemingly rational approach was not ecologically rational: individuals with hoarding and healthy individuals earned about the same amount of money, but it took individuals with hoarding a lot longer to do it: additional cognitive costs did not lead to additional benefits.

Cognitive-Behavioral Treatment of Hoarding in Youth: A Case Illustration

Hoarding in children is associated with more severe ancillary psychopathology, and has poor treatment outcome. At present, there are no empirically established procedures for treating hoarding in youth. The present case illustration is of a 10-year old child ("Grace") who presented for treatment with significant hoarding related to academic concerns and additional unrelated symptoms of obsessive-compulsive disorder (OCD). Grace was treated with cognitive behavior therapy (CBT) primarily comprising exposure with response prevention, behavioral experiments, and cognitive therapy, along with a program of reinforcement delivered by her parents to maintain her motivation for therapy. After 23 sessions and one booster session, Grace's symptoms improved significantly, with gains maintained at 1-year follow-up. In addition to the benefits of the specific interventions chosen, the role of therapist-patient/parent alliance as a contributory factor for good outcome is emphasized. As hoarding is underinvestigated in youth, suggestions for further investigation are offered.

An investigation of delay and probability discounting in hoarding disorder

Behavioral impulsivity may be a mechanism of hoarding disorder (HD). A commonly used and well-validated measure of impulsivity is the delay and probability discounting task, which consists of making decisions about receiving monetary rewards after varying delay intervals and delivery probabilities. We compared delay and probability discounting and self-reported behavioral impulsivity in 81 patients with a primary diagnosis of HD and 45 nonclinical controls. HD participants completed the impulsivity measures before and after 16 weekly sessions of cognitive-behavioral therapy (CBT), whereas control group participants completed the measures before and after a 16-week waiting period. Despite the fact that self-reported impulsivity was greater in the HD group than the control group, delay and probability discounting did not differ between groups. Additionally, while self-reported behavioral impulsivity improved over the course of CBT in HD participants, delay and probability discounting did not change during treatment. Furthermore, higher delay discounting scores (i.e., greater preference for immediate rewards, indicating greater impulsivity) were associated with lower hoarding symptom severity. The findings suggest that self-reported impulsivity, but not objective performance on a behavioral impulsivity task, may be impaired in HD, and are discussed in terms of cognitive and affective factors in decision-making.

Comparing clinical characteristics and treatment outcomes between Veterans and non-Veterans with hoarding disorder

BACKGROUND

Because Veterans have higher rates of mental health conditions and both physical and mental health comorbidities are known to affect treatment outcomes, the purpose of this investigation was to compare the rates of risk factors for poor hoarding treatment outcomes between Veterans and non-Veterans with hoarding disorder (HD). This is the first study to investigate differences between Veterans and non-Veterans with HD.

MATERIAL AND METHODS

Baseline data were used from three different treatment studies of adults with hoarding disorder (n = 159). Demographic characteristics, baseline hoarding symptom severity, baseline medical and psychiatric comorbidities, and treatment attrition and response were compared between Veterans and non-Veterans.

RESULTS

Veterans were significantly less likely to be employed than non-Veterans. Veterans did not report significantly more severe hoarding symptoms at baseline when compared to non-Veterans. Veterans reported having a greater mean number of overall medical and psychiatric comorbidities. Veterans were more likely than non-Veterans to meet criteria for major depressive disorder and post-traumatic stress disorder. There was no significant difference in the rate of attrition between Veterans and non-Veterans and Veterans were not significantly more likely to be classified as treatment responders.

CONCLUSION

Many similarities were observed between the two groups, including demographic characteristics, hoarding symptom severity, and rates of treatment response. Given that Veterans with HD may suffer from greater medical and psychiatric comorbidities, clinicians should ensure that their clients are receiving adequate medical care and that any other psychiatric comorbidities should be addressed in conjunction for treatment with HD.

Can Occupational Therapy Address the Occupational Implications of Hoarding?

Hoarding is often described as a medical disorder, defined by a persistent difficulty in discarding possessions and associated high levels of emotional distress when forced to part with these. This article will discuss how having a different view of hoarding, seeing hoarding as a daily occupation which provides value, purpose, and meaning and with a relationship to self-identity and life purpose, could offer alternate interventions to support an individual who hoards. The article will consider the components of hoarding activity and how these relate to health and wellbeing and doing, being, belonging, and becoming as understood by occupational therapists. The article will consider what occupational therapy, a profession which considers a person's daily occupations, the things that occupy their time and which give meaning to their existence, could offer as an alternative to current hoarding interventions. Proposals for occupational therapy interventions will be suggested which would support occupational choice, support engagement in activities which have more positive outcomes on a person's health, and seek to address barriers which limit engagement and occupational performance in activities within the person's home environment.

Presidential Address: Team Science Across Disciplines: Advancing CBT Research and Practice on Hoarding

This presidential address focuses on the recent history of research and practice on hoarding disorder (HD) as a potential model for coordinating interdisciplinary teams of professionals within and outside mental health fields to advance scientific efforts to understand and resolve mental health problems. To identify, assess, and intervene with clients who have HD, psychologists, social workers, psychiatrists, and other service professionals are needed, including those in public health, housing, medicine, aging and protective services, fire, safety, and animal protection. Research findings and practice methods developed by many of my colleagues highlight the various skills of these diverse disciplines and fields. Of particular interest are multimethod assessments and CBT interventions that span individual, group, and family treatments, delivered in the office, at home and via the web by mental health and other professionals, as well as peers. Outcomes are positive, but there remains much work to do to improve understanding and intervention outcomes.

Effectiveness of a 'Workshop on Decluttering and Organising' programme for teens and middle-aged adults with difficulty decluttering: a study protocol of an open-label, randomised, parallel-group, superiority trial in Japan

INTRODUCTION

Hoarding disorder can cause problems with work performance, personal hygiene, health and well-being. The disorder is a growing social problem in Japan. Having difficulty discarding rubbish, decluttering and organising can signal a future hoarding disorder, and early intervention is important. We developed an educational workshop on decluttering and organising for teens and adults with difficulty organising. The objective of this study is to evaluate the effectiveness of a workshop for reducing clutter and improving quality of life among younger people with difficulty decluttering and organising.

METHODS AND ANALYSIS

An open-label, parallel-group, randomised controlled trial will be conducted among volunteers aged 12-55 years with mild difficulty decluttering and organising. Those in the intervention group will attend the workshop and receive a visit from a professional cleaning company to declutter their living space. The control group will have only the latter. The primary outcome will be the score on the Japanese version of the Saving Inventory-Revised. Secondary outcomes will be scores on the Clutter Image Rating Scale, the Japanese version of the Rosenberg Self-Esteem Scale and the Roles of Private Space Scale. The results will be examined for differences between the two groups in changes from baseline to 7 months. We will examine crude effects and adjust for gender and age using a general linear model for continuous variables and a logistic regression model for dichotomous variables. Sample size was calculated assuming a significance level of 5% (two tailed), a power of 80% and an effect size of 0.75. In total, 60 subjects (30 in each group) will be required.

ETHICS AND DISSEMINATION

The study protocol has been approved by the Medical Ethical Committee of Teikyo University (No. 15-065). The findings will be disseminated widely through peer-reviewed publication and conference presentations.

Council tenancies and hoarding behaviours: A study with a large social landlord in England

Hoarding behaviours are highly stigmatised and often hidden. People with problematic hoarding behaviours have a higher rate of mental health and other healthcare and social services utilisation. Hoarding is a community health problem, one factor being housing insecurity. Hoarding behaviours represent significant burden to housing providers, impact the community and dealing with it involves multiple community agencies. This study with a city council in England with a large housing stock (over 14,000 properties) in summer 2021 sought to understand the nature, circumstances and extent that hoarding presents. We developed a reporting system and conducted 11 interviews with housing officers in which they described a case to explain their involvement. Our report details the nature of 38 people who hoard: 47% had a known disability or vulnerability, 34% presented a fire and environmental risk, 87% lived alone and 60% were resident in flats. Our qualitative themes are: Working with others, Balancing an enforcement approach, Feeling conflicted, Complex needs of people who hoard and Staff needs. The cases described by the housing officers are combined into six case studies and illustrate the complex, multi-agency circumstances around decision making and risk stratification. Our findings point to housing officers as frontline professionals dealing with a public health and social care issue which is often the manifestation of complex life histories and mental health conditions. We suggest a greater focus on risk stratification and a more holistic approach to hoarding cases to effectively deal with this most complex of community health and social care issues.

Cognitive behaviour therapy with compulsive hoarding: a single case study

The current case study used cognitive behaviour treatment (CBT) for the management of a 35-year-old, married man who presented with complaint of compulsive hoarding. The complaint of compulsive hoarding (excessive acquisition, difficulty in discarding saved material and cluttering) was accompanied by feeling of anger, sad mood, low confidence, decreased sleep and appetite, poor problem solving ability, indecisiveness and interpersonal conflicts. The study was approved by the institutional research committee (Departmental Doctoral Programme Committee) and followed by the university research committee (Advance Studies and Review Board) as academic requirement for the duration of 2013-2020. Written consent was also taken from the individual to publish the results of the case. Twenty-eight CBT sessions of one-hour duration were conducted, over a period of six months. Management plan mainly comprised decision-making techniques, cognitive restructuring, behavioural experiments, problem solving and social skills training. The individual was assessed on pre, mid, post and follow up levels. Assessment showed significant decrease in the symptoms. The present case report will help clinicians dealing with individuals with compulsive hoarding and its associated features, effectively with CBT.

Hoarding disorder and the legal system: A comparative analysis of South African and Dutch law

Hoarding is an internationally recognised disability. Those who suffer from hoarding behaviour can be comfortably brought within the definition of disability found in the Convention on the Rights of Persons with Disabilities and should be provided with "reasonable accommodation" where doing so does not place an unjustified burden on others. However, hoarding also poses a threat to public health, and hoarders' behaviour may infringe on the rights of their neighbours and landlords. Thus, through their behaviour, hoarders may ultimately come into conflict with various areas of law, including neighbour law, housing law as well as administrative law. This article examines how hoarding may be addressed by the law in both South Africa and the Netherlands. It seeks to answer to what extent hoarders are provided with "reasonable accommodation" when their behaviour brings them into conflict of the law in these two jurisdictions. It also takes cognisance of the need to balance the provision of "reasonable accommodation" with the rights of neighbours and landlords. Finally, it seeks to assess which of the two jurisdictions provides the most balanced approach to handling hoarding, in light of the need for therapeutic jurisprudence.

[Treating hoarding disorder in a 12-year-old boy]

In this case report hoarding disorder is described in a 12-year-old boy who suffered from obsessive collection of things. The disorder is a separate diagnostic entity in DSM-5, and it will probably be a separate disorder in ICD-11 called hoarding disorder. The disorder is generally considered difficult to treat, but this case report describes significant reduction in hoarding symptoms on cognitive behavioural therapy and treatment with selective serotonin reuptake inhibitors.

Psychological mechanism of acceptance and commitment therapy and rational emotive behavior therapy for treating hoarding: Evidence from randomized controlled trials

Hoarding is a common problem behavior worldwide and is detrimental to the physical and mental health of individuals and groups. Currently, effective interventions for hoarding are cognitive-behavioral therapies, but their post-intervention efficacy is questionable, and the available research does not examine the mediating variables of the effects of interventions on clinical outcomes. Moreover, current research on hoarding has focused on Western countries. Therefore, there is a need to investigate the efficacy of other forms of cognitive behavioral therapy on hoarding as well as other psychological outcomes related to hoarding and mediating variables that contribute to its effectiveness in different cultural contexts. One hundred thirty-nine college students with higher hoarding behaviors were randomly divided into three groups: 45 in the Acceptance and Commitment Therapy (ACT) group, 47 in the Rational Emotive Behavior Therapy (REBT) group, and 47 in the control group. They completed the Saving Inventory-Revised (SI-R), Obsessive-Compulsive Symptom Scale (OCSS), Difficulties in Emotion Regulation Scale (DERS), Experiences in Close Relationships Inventory-Attachment Anxiety Subscale (ECR), Depression Anxiety Stress Scales (DASS-21), Acceptance and Action Questionnaire II (AAQ-II), and Cognitive Fusion Questionnaire (CFQ) before and immediately after the intervention. The results showed that ACT and REBT improved individuals' psychological flexibility, cognitive fusion, acquisition-difficulty discarding, clutter, negative affect (anxiety, depression, stress), attachment anxiety, obsessive-compulsive disorder, and difficulty in emotion regulation compared to the control group. In addition, ACT was more effective than REBT in improving psychological flexibility and reducing hoarding, cognitive fusion, depression, stress, and obsessive-compulsive disorder; there were no significant differences between the two in anxiety and emotion regulation difficulties. Furthermore, psychological flexibility is a mediator of the effect of ACT and REBT on some behavioral and psychological outcomes (hoarding, negative affect, attachment anxiety). Limitations were discussed.

"Falling between the cracks": Investigating the competing challenges experienced by professionals working with people who hoard

Hoarding disorder is characterised by both the distress associated with discarding and the resulting accumulation of possessions that clutter the home environment, and represents a substantial public health and social problem, requiring an effective multi-agency response. Although a recognised psychiatric condition since 2013, hoarding disorder is under-recognised within mental health treatment provision, and evidence-based treatment pathways are lacking. This study aimed to explore multi-agency working in practice and similarities and differences in how hoarding support is perceived across a broad range of front-line professionals. 35 semi-structured interviews representing a wide range of services from health, social care, housing, and the voluntary sector were conducted and analysed thematically. Three overarching themes are reported: Unique challenges of supporting people who hoard, Conflicting needs of client vs. needs of the organisation, Managing role boundaries and psychological tensions. Findings consistently highlight the challenges specific to these cases. However, they also point to a lack of consensus between professional groups in terms of perceived problems and risks to be addressed. Collaborating effectively with others to meet the psychological needs of clients while ensuring risk mitigation and addressing broader organisational, environmental, and community concerns was found to be a key challenge and associated with often going beyond designated role boundaries to support the person. Our findings point to a need for greater support and training of a diverse set of professionals in psychological models of people who hoard to enhance knowledge, awareness, and confidence of the psychological dimensions of hoarding disorder, and to support them in feeling more emotionally and practically prepared. The results indicate a need for greater integration of mental health measures in the assessment of hoarding cases, and to ensure adequate care pathways with dedicated psychological support along with assignment of case workers/coordination.
